So I unlocked this computer by reading the ITE chip and writing the same file back to the chip. Of course I know in doing this the System Serial UUID and Model Number would get erased as well. Here's a picture IMG_3910.jpg

Every time I try and write the DIM information like MTM, Serial, Model Number with any tool like U1 tool it says EEPROM Write Protected. Anyone know how to fix this issue?
